Eric Cowell - the 4-year-old son of music mogul Simon - dressed as his famous father on Tuesday, hilariously impersonating his dad for World Children's Day.

In support of Unicef UK, Simon, 59, and Eric's mum Lauren Silverman, 41, allowed their son to 'make all of the decisions for the day', to honor the occasion, which 'is a day of action for children, by children'.
